Hi. I use Website Auditor to analyse my Joomla site and a resource was shown as giving a 500 error. Using WebSiteOptimization.com, the cause was identified (see screenshot):
The url is https://tapestrycondo-sg.com/templates/enterprise/XTC/css.php?id=14
I have not set any page rules and cache level is set to Standard. The htaccess file is original from the Joomla package; it has no additional lines added. cpanel error logs do not reveal anything.
Anyone has an idea on how to resolve this?
